Understanding the Use of Software Today
A software is a collection of computer algorithms, programs, procedures and documentation that provide instructions that tell the computer what do and how to it. Program software performs its functions by providing directions to a hardware (physical device) or serve as an input to other software. The term software sometimes includes data like film, tapes, application software and records traditionally associated with computers.
A computer uses a machine language called binary. Other computer languages include high level and assembly language, which are compiled into machine language object code using an assembler. Each processor consists of executable binary codes that order a computer to change its states in a given sequence.
There are many types of software, which includes web pages, desktop applications or Smalltalk. Web pages are software like XML, Perl and HTML. Microsoft Word and Open Office are good examples of desktop applications that use languages like C, Java and C#.
SYSTEM SOFTWARE.
System software operates the computer hardware and provides a platform in which application software works in. Examples of system software are operating systems, drivers, window systems and utilities. System software manages two or more hardware to work together. Another function of the system software is to safely partition computer memory and processor time.
PROGRAMMING SOFTWARE.
Programming software is used as a programming tool by software developers to create, debug or to support other computer applications. Examples of such software are debuggers, compilers and linkers. These programming tools assist in writing computer programs.
APPLICATION SOFTWARE
Application software allows the computer to perform specific data processing jobs. It performs in tasks that benefit from computation like the Internet browser.
EXECUTION
Software has to be run/loaded in the computer’s hard drive or memory for it to work. NB, poor quality software can delete or crash existing programs and files. When loading a software, the instructions pass from the application software to system software and finally to the hardware which hold it as machine code.
